Duration to HH:MM:SS for Zapier export

I need some coding help. I have a duration field, I want it that way because its used throughout to add/subtract through my multiple tables, however the final step is exporting out through Zapier through an email. This produces the duration field which is in HH:MM:SS to a long integer of seconds so 3:15:23 turns into 11723. I need a formal that converts “11723” seconds into “3:15:23”
